ELECTRIC LAM P.

.SPECIFICATION forming part of Letters Patent N o. 712,551, dated November 4, 1902.

Application filed March 2l, 1902, Serial N01 99,244. (No model.)

fo all whom, it 7mo/y concern:

Be it known that I, ANTON KUSEBAUCH, a citizen of the United States, and a resident of Edgewood Park, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Electric Lamps, (Case No. 1,011,) of which the following is a specification.

Myinvention relates to electric lamps, and

lo more particularly to housings for lamps of the type in which the light-giving members, usually termed glowers, are conductors ot' electricity only when heated to comparatively high temperatures, though not necessarily restricted to lamps ot' this specific type.

The object of myinvention is to provide a housing which shall be weatherproof and have a large amount of radiating-surface and also one which will permit of inspecting and 2o repairing the operating parts of the lamps and also the removal and replacement of certain parts of the lamp structure without interfering with or removing the lamp structure as a whole from its operative suspended posi- :5 tion.

A further objectof the invention is to provide a simpleand eicient means whereby the globe which surrounds the glowers and heaters may be lowered with reference to that 3o portion of the housing upon which it is supported and swung away from the parts inclosed by it in order that such attention as may be necessary may be given to said parts.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a longitudinal section of the honsing'and a portion of the globe, the operating parts of the lamp, so far as shown, and the remainder of the globe being shown 4o in side elevation. Fig. 2 is a plan View of the cylindrical body portion of the housing, the operating parts of the lamp, except the base-plate or ring upon which they are supported, being removed. Fig. 3 is a side elevation of the lamp shown in Figs. 1 and 2, but drawn to a smaller scale and showing the cylindrical portion of the housing and the globein their lowered' positions.

The details of construction, as illustrated 5o in the drawings, are as follows: The upper portion of the housing 1 is in the form of a dome-shaped metal cap 2, which is corrugated, as indicated, in order to provide a maximum amount of radiating-surface, and has a ring 3, by means of which the lamp is suspended in operative position. 'The cap 2 is also provided with two holes 4, in which are fitted bushings 5, of porcelain or other suitable insulating and weatherproof material, which are perforated to receive condutt- 6o ing-rods o, the supply-conductors 7 being connected to the outer ends of these rods and the glower and heater-wires (not shown) being connected to the inner ends of these rods.

The cap 2 is provided with a plurality of depending arms 8, three being employed in the lamp here shown, and this is a suitable number andall that will generally be found necessary, although any other number may ob- 7o viously be employed if desired. The baseplate 9 for supporting the glower and heaterholder 10, the inner globe 11, the cut-out 12, and the ballast devices (not shown) is fastened tothe lower ends of the arms 8 by means 75 of screws 13, as indicated in Figs. 1 and 2.

The body portion 14 of the housing, which is of general cylindrical form, is also corrugated for the purposes of heat radiation and is fastened to the upper ends of the arms 8 by 8o means of screws 15. The body portion 11 is also provided adjacent to its upper end with inwardly-projecting pins 16, (here indicated as screws;) but the particular' form of .these pins is obviously immaterial so long as they project a proper distance into the interior of the housing and are all in substantially the same horizontal plane. The body portion 1i of the housing is also provided near its lower end with a boss 17, having a vertical hole 18, 9o through which projects a rod 1f), the upper end of the rod being provided with a suitable projection, (here shown as a cotter-pin 20.) The lower end of the rod has a hinge connection with a metal band 2l, with which the 95 neck of the globe 22 is provided. The globe is held in operative position ,by means of screws 23, three being shown in the drawings, which are supported by the body portion 14 of the housing and the inner ends of which roo engage with notches 2l, formed by lips cut l the operating mechanism of an electric lamp from the metal band 21, thus providing an l comprising a cap having holes containinginelastic support for the globe.

It will be seen by reference to Figs. l and 3 of the drawings that when it is desiredto gain access to the operating parts of the lamp for the purpose of investigation or repairs or forV replacement of any of the parts the body portion of the housing may be released from the cap by withdrawing the screws l5, and the said body portion may then be lowered until the pins 16 engage the upper surface of Ithe base-plate 9, thus preventing further lowering of this part ofthe housing. Access is y thus given to the operating portions of the lamp which are supported upon and above the base-plate 9.

If it is desired to inspect or repair the parts which are located below the base-plate 9, the screws 23 may be withdrawn from the notches in the metal band 2l, and the globe 22 may then be lowered bodily until the pin 2O in the upper end of the rod 19 engages with the upper side of the boss 17. The globe may then be swung to one side upon its hinge, as indicated in Fig. 3. It' will thus be seen that ready access is secured to all parts of the lamp and that when the parts are in operative position, as indicated in Fig. l, the housing is substantially weatherproof, and is thus particularly well adapted for outdoor service.

Modifications in details of construction may obviously be made without departing from the invention, and I therefore desire it to be understood that no limitations are to be imposed except such are imposed by the prior art or specified in the claims.

I claim as my invention- 1. An electric-lamp housing comprising a cap having extensions for supporting the operating parts of the lamp, a longitudinallymovable body portion supported by said extensions and having stop-pieces, and adjustable means for fastening the body portion to the cap extensions and releasing the salme.

2. An electric-lamp housing comprising a cap having depending arms for supporting the operating parts of the lamp and a body portion detachably fastened to said cap and having supporting-stops which come into action when said body portion has been moved a predetermined distance away from the cap, in combination with a globe, a guide having a sliding connection with the body portion of the housing and provided with a limitingstop at its upper end and a hinge connection with the globe at its lower end.

3. An electric-lamp housing comprising a corrugated cap from which the operating parts of the lamp are suspended and a corrugated body portion attached to said cap and longitudinally movable with reference thereto, in combination with a globe and a rod to which said globe is hinged, said rod beingsupported by the body portion of the housing and movable longitudinally with reference thereto.
